Initializers of global data that can appear multiple TUs (static data members of class templates or __declspec(selectany) data) are now in a comdat group keyed on the global variable being initialized. On non-Windows platforms, this is a code size and startup time optimization. On Windows, this is necessary for ABI compatibility with MSVC. Fixes PR16959.
